Khemeia, or ‘al-kimiya’ in Arabic,
was developed with novel ideas and much enthusiasm in Arab countries.
Jabir ibn-Hayyan (c. 719-813 AD)
soon became the most influential alchemist of the Arabic world.
His work included descriptions of ammonium chloride, acetic acid and
nitric acid, as well as furthering the field of classic alchemy.
Persian physician Al-Razi (c. 850-925 AD) (see left) was
credited with the application of plaster of Paris to holding broken bones in
place, thus promoting the use of chemistry in medicine.
